Abstract

A fuse box in which wire distribution blocks each have a receiving chamber and a metal wire clip in the receiving chamber, and tightening up screws are respectively threaded into the wire distribution blocks to compress the respective metal wire clips and to force the respective metal wire clips into positive engagement with respective electric wires. Metal spring plates are mounted in respective oblique insertion holes in the wire distribution blocks to hold fuses in a tilted position, so that less vertical installation space is occupied.

Claims

exact text as granted — not AI-modified
What the invention claimed is:  
     
       1. A fuse box comprising: 
       a mount;  
       a plurality of wire distribution blocks respectively fixedly mounted on said mount, said wire distribution blocks including one power input distribution and a plurality of power output distribution blocks each having at least one receiving chamber at one side;  
       a plurality of metal wire clips respectively mounted in the receiving chamber of each of said wire distribution blocks and adapted to secure a core of an electric wire, said metal wire clips each comprising two horizontal clamping walls horizontally disposed at different elevations, and two vertical support walls bilaterally disposed between said horizontal clamping walls, said vertical support walls and said horizontal clamping walls defining a receiving space adapted to receive the core of an electric wire, said horizontal clamping walls each having a plurality of transverse ribs formed on an inner surface thereof and having a front end terminating at a serrated portion forming a plurality of teeth projections for conformingly and securely engaging an insulative shell of an electric wire; and,  
       a plurality of tightening up screws threaded into respective screw holes formed in said wire distribution blocks for depressing said metal wire clips, the serrated portions of each said metal wire clips being thereby forced into engagement with an insulative shell of the electric wire inserted into one of said wire distribution blocks.  
     
     
       2. The fuse box as claimed in  claim 1  wherein said serrated portions of said metal wire clips each extend to generally form an acuate concavity for engaging a circular cross section of the electric wire in conformed manner. 
     
     
       3. A fuse box comprising: 
       a mount;  
       a plurality of wire distribution blocks respectively fixedly mounted on said mount, said wire distribution blocks including one power input distribution and a plurality of power output distribution blocks each having at least one receiving chamber at one side;  
       a plurality of metal wire clips respectively mounted in the receiving chamber of each of said wire distribution blocks and adapted to secure a core of an electric wire, said metal wire clips each comprising two horizontal clamping walls horizontally disposed at different elevations, and two vertical support walls bilaterally disposed between said horizontal clamping walls, said vertical support walls and said horizontal clamping walls defining a receiving space adapted to receive the core of an electric wire, said horizontal clamping walls each having a plurality of transverse ribs formed on an inner surface thereof and having a front end terminating at a serrated portion for conformingly and securely engaging an insulative shell of an electric wire; and  
       a plurality of tightening up screws threaded into respective screw holes formed in said wire distribution blocks for depressing said metal wire clips, the serrated portions of each said metal wire clip being thereby forced into engagement with an insulative shell of the electric wire inserted into one of said wire distribution block;  
       said power input distribution block has an oblique insertion slot and a metal spring plate mounted in the oblique insertion slot for receiving one terminal of a fuse, and said power output distribution blocks each have an oblique insertion slot corresponding to one oblique insertion slot of said power input distribution block and a metal spring plate mounted in the oblique insertion slot for receiving one terminal of a fuse.  
     
     
       4. A fuse box comprising: 
       a mount;  
       a plurality of wire distribution blocks respectively fixedly mounted on said mount, said wire distribution blocks including one power input distribution and a plurality of power output distribution blocks each having at least one receiving chamber at one side;  
       a plurality of metal wire clips respectively mounted in the receiving chamber of each of said wire distribution blocks and adapted to secure a core of an electric wire, said metal wire clips each comprising two horizontal clamping walls horizontally disposed at different elevations, and two vertical support walls bilaterally disposed between said horizontal clamping walls, said vertical support walls and said horizontal clamping walls defining a receiving space adapted to receive the core of an electric wire, said horizontal clamping walls each having a plurality of transverse ribs formed on an inner surface thereof and having a front end terminating at a serrated portion forming a plurality of teeth projections for conformingly and securely engaging an insulative shell of an electric wire; and  
       a plurality of tightening up screws threaded into respective screw holes formed in said wire distribution blocks for depressing said metal wire clips, the serrated portions in said metal wire clips being thereby forced into engagement with an insulative shell of the electric wire inserted into one of said wire distribution block;  
       a center distribution block fixedly mounted on center of said mount for connection to said power output distribution blocks by fuse for transmission power supply from said power input distribution block to said power output distribution blocks; and,  
       a metal conductive plate connected between said center distribution block and said power input distribution block for enabling power supply to be transmitted from said power input distribution block to said center distribution block and then from said center distribution block to said power output distribution blocks by fuse coupling.  
     
     
       5. A fuse box comprising: 
       a mount;  
       a plurality of wire distribution blocks respectively fixedly mounted on said mount, said wire distribution blocks including one power input distribution and a plurality of power output distribution blocks each having at least one receiving chamber at one side;  
       a plurality of metal wire clips respectively mounted in the receiving chamber of each of said wire distribution blocks and adapted to secure a core of an electric wire, said metal wire clips each comprising two horizontal clamping walls horizontally disposed at different elevations, and two vertical support walls bilaterally disposed between said horizontal clamping walls, said vertical support walls and said horizontal clamping walls defining a receiving space adapted to receive the core of an electric wire, said horizontal clamping walls each having a plurality of transverse ribs formed on an inner surface thereof and having a front end terminating at a serrate portion for conformingly and securely engaging an insulative shell of an electric wire;  
       a plurality of tightening tip screws threaded into respective screw holes formed in said wire distribution blocks for depressing said metal wire clips, the serrated portions of each said metal wire clip being thereby forced into engagement with an insulative shell of the electric wire inserted into one of said wire distribution blocks;  
       a center distribution block fixedly mounted at a center of said mount for connection to said power output distribution blocks by fuse for transmission power supply from said power input distribution block to said power output distribution blocks; and,  
       a metal conductive plate connected between said center distribution block and said power input distribution block for enabling power supply to be transmitted from said power input distribution block to said center distribution block and then from said center distribution block to said power output distribution blocks by fuse coupling;  
       said power output distribution blocks each have an oblique insertion slot and a metal spring plate mounted in the respective oblique insertion slot for receiving one terminal of a respective fuse, and said center distribution block has a plurality of oblique insertion slots corresponding to the oblique insertion slot of each of said power output distribution blocks and a plurality of metal spring plates respectively mounted in the respective oblique insertion slots for receiving one terminal of a respective fuse.
